Hacksaw frame is used along with a blade to cut metals of different sections and is specified by the type and maximum length of the blade that can be fixed.

The distance between the adjacent teeth is known as the pitch of the blade.

Important Points

A hacksaw blade is made of either low alloy steel (LA) or high-speed steel (HSS) and is available in standard lengths of 250 mm and 300 mm.

The selection of the blade depends on the shape and hardness of the material to be cut.

Type of hacksaw blades

  • All-hard blade: The full length of the blade between the pins is hardened
  • Flexible blade: Only the teeth are hardened. Because of their flexibility, these blades are useful for cutting along curved lines. Flexible blades should be thinner than all hard blades.
